40Requirements
41************
42
43This shield can only be used with a board which provides a configuration
44for Mikro-BUS connectors and defines node aliases for SPI and GPIO interfaces
45(see :ref:`shields` for more details).
46
47Programming
48***********
49
50Set ``--shield mikroe_eth3_click`` when you invoke ``west build``. For example:
51
52.. zephyr-app-commands::
53   :zephyr-app: samples/net/dhcpv4_client
54   :board: mikroe_stm32_m4_clicker
55   :shield: mikroe_eth3_click
56   :goals: build
